In the case of plants with conventional long kilns, the challenge is above all to realize an injection system that is able to successfully master the interface between the stationary valve skid unit and the rotating kiln. Due to the eccentricity of the long kiln, the center of kiln entry moves during operation. It is moved further still by thermal expansion. These factors and their consideration alone shows just how complex the task is.
A further challenge is the selection of the material for the nozzle lances and other components in the kiln. These are constantly rotated during the firing phase by the hot material within the kiln.
The scope of delivery for these injection systems covers the customized design and supply of valve skid units, pipe systems for the decoupling of rotating and static components, pipelines in and on the kiln as well as injection lances within the long kiln.
